我的Python脚本有一个问题。当我运行spider scrapy runspider Myspider时，它可以工作，但如果我从主文件运行它，我会出现以下错误：KeyError: 'driver'个
设置文件：

SELENIUM_DRIVER_NAME = 'chrome'

# SELENIUM_DRIVER_EXECUTABLE_PATH = '/home/PATH/OF/FILE/chromedriver'

SELENIUM_DRIVER_ARGUMENTS=['--headless']

DOWNLOADER_MIDDLEWARES = {
    'scrapy_selenium.SeleniumMiddleware': 800
}

我的spider文件：

class MySpider(scrapy.Spider):
    name = 'my_spider'

    def __init__(self, list_urls, *args,**kwargs):
        super(my_spider, self).__init__(*args,**kwargs)
        self.urls = list_urls

    def start_requests(self):
        for url in self.urls:
            yield SeleniumRequest(
                url = url['link'],
                callback = self.parse,
                wait_time = 15,
            )

和我主文件：

import scrapy
import classListUrls
from scrapy.crawler import CrawlerProcess
from dir.spiders import Spider

URL = "example.com"
urls = classListUrls.GenListUrls(URL)

process = CrawlerProcess()
process.crawl(Spider.my_spider, list_urls = urls.list_urls())
process.start()

我不明白为什么会出现这种错误。
